Did you know that in the original Starcraft 1 - you could enter a cheat-code "operation cwal" which would reduce the building and research time of all your units, structures and upgrades by 500%? Well, operation cwal was a community that formed in semi-protest against Blizzard taking so long to perfect Starcraft 1. Operation Can't Wait Any Longer. In Starcraft 2... the marine epicly opens the show with 'Hell... it's about time'...
The Reaver uesd to be called the Trilobyte in alpha builds of Starcraft 1. The Reaver was going to be featured in Starcraft 2 multiplayer, but was replaced by the Colossus at the last minute. There were rumours that you could control the Reaver in the Wings of Liberty campaign - but this seems to have been proved untrue. Since you were pretty limited to Zealots, Stalkers, Collosi, Probes and Zeratul.
The Protoss Stargate was going to be called the Nexus! Imagine that.
The Third Screenshot clearly shows a Terran air unit... but it is named the Phoenix... Maybe the current Protoss Phoenix in Starcraft 2 is the final product of a brain-fart in the mid 1990's?
The Confederacy in Starcraft 1 had a clandestine secret police called Nova Squadron.
Terran Marines were called Marauders in the Starcraft 1 Alpha Build...
Sammuro is a fruit from Aiur. I doubt it will be included in Auir Chef...
Starcraft 1 had three damage types: Explosive, Normal and Concussive.
Despite being the most popular map... ever... Big Game Hunters did not make it into Starcraft 2.
None.
